Set Power up FSB frequency to 100MHz if the user wants to run the CPU at an FSB frequency of 100MHz or higher. This setting will allow the user to run the CPU at a higher FSB frequency, especially when the user wants to urn a 66MHz FSB CPU at 100MHz and higher FSB frequencies.

Hardware Installation

Note: The “Manual”mode setting facilitates FSB over-clocking. Doing so will however force your CPU to operate out of its specifications, and therefore SOYO can not guarantee the proper function of your system.

Step 5. Set the CPU Frequency

This Motherboard does not use any jumpers to set the CPU operating frequency; theCPU settings can be changed through the BIOS [SOYO COMBO SETUP]. Please refer to Chapter 3 “Quick BIOS Setup”for details on setting the CeleronTM processor frequency.

Step 6. Set for JP9 FWH Boot Block Write-Protect

Setting this jumper to open will prevent the boot block area of the FWH (FirmWare Hub) chip from being written data into such that it is write-protected from unwanted or abnormal write activity.

Note: In some rare cases, the boot block area will need to be flashed to complete the BIOS upgrade procedure. Setting JP9 to open will cause incomplete BIOS update in that case.
